摘要
运用分析化验、储层测试等多种资料对羌塘盆地中上侏罗统碳酸盐岩储集层的成岩演化特征进行研究。分析了八种成岩作用类型。在成岩作用研究的基础上 ,分出六种成岩相类型 ;探讨了各种成岩相的岩性、物性等微观特征及与沉积相类型之间的关系 ;总结出成岩演化序列 ;最后讨论了各种成岩作用对储集层物性的影响。
Characteristics of Diagenetic evolution of carbonate reservoir in upper and middle Jurassic in Qiangtang Basin are studied in the paper using data of an alyses, chemical examinations and reservoir measurement, etc. Eight types of di agenesis are analyzed in detail.Diagenetic stages have been concluded.Six types of diagenetic faces are r ecognized and the relation between microstructures of each diagenetic face mainl y including lithology,porosity and permeability of the types of sedimentary face is studied.Succession of diagenecic evolution are summed up. In the end of the article the influences of all kinds of diagenesis to porosity and permeability a re discussed.\;Subject
